Machine intelligence is the last invention that humanity will ever need to make.

When we are headed the wrong way, the last thing we need is progress.

Are you living in a computer simulation?

For healthy adult people, the really big thing we can foresee are ways of intervening in the ageing process, either by slowing or reversing it.

Far from being the smartest possible biological species, we are probably better thought of as the stupidest possible biological species capable of starting a technological civilization - a niche we filled because we got there first, not because we are in any sense optimally adapted to it.

The challenge presented by the prospect of superintelligence, and how we might best respond is quite possibly the most important and most daunting challenge humanity has ever faced. And-whether we succeed or fail-it is probably the last challenge we will ever face.

Human nature is a work in progress.
